Antibody catalysis based on functional mimicry.

Abstract

Approaches aiming at eliciting antibodies (Abs) that catalyze specific chemical transformations are numerous. Most of the developed methods are based on the chemical steps of the reaction catalyzed rather than on the structure of known enzyme active sites. The authors have developed an approach that rests on the mimicry properties of the idiotypic network of immune regulation. Recent results, together with the existence of natural catalytic Abs in autoimmune diseases, indicate the need to better understand the regulation properties of immune response, in order to improve the efficiency of tailor-made catalytic Abs.
